AUTOMOBILE naIvING-Gzan. 'i

To all whom it may concern: Be it known that I, CHARLES C. BETTEN- f' y Hausen, of Princeton, in the county of Lanthis type.

caster and State of Nebraska, have invented certain new anduseful Improvements in Automobile Driving-Gear, which are described in the following specification and are illustrated by theaccoxnpanying drawmss- My invention relates to mechanism for driving the forward .wheels of automobiles positively. y

It is one of the objects of the invention to utilize in mechanism of this rkind an axle of that type which is commonly known as a dependent. or drop axle, and thereby-to attain all the special. advantages which result from the use of a forward axle of that kind.

It is another object of the invention to simplify the construction of driving gear of It is another object of the invention to use at each end of the driven forward axle of a motor vehicle a earing,- whose intermediate or idle` member, being constructed with oppositely'directed faces, shall have. the shaft of that member supported beth in the middle and also at each end of that shaft.

It is another object of the invention to inclose the working members of the knuckle gearin in separate oil chambers, which are pivote one above the other by the shaft of such intermediate member.

These several objects I accomplish simultaneously. i

The best manner in which I have contemplated applying the principles of the invention, areV shown in said drawings; in which- V F'gure 1 is a rear elevation of the forward truck of au automobile, constructed 'in accordance with those principles. Fig. 2 is a plan Yview of the saine. Fig. 3 is an enlarged detail in vertical cross-section on line w-w of Fig. 1. Fig. 4 is an axial vertical section through the hub of one of the traction wheels.

In these views the forward wheels of the vehiclel are denoted by the numerals l and 1. Zach of ilu-se wheels has a hub 2, turn ingr upon the bearing sleeve 20, and provided with a .si-new cap 21. Sleeve 20 ls the shank of a volte 3, which comprises a casing Ll and a dependent bracket Within sleeve 20 runs a stub axle 6. which carries at its inner end a bevel gear located in said casing 4, and

i engages atl its outer end'the outer end ofv hub 2 by 'a pin 22l or by other convenient means. The iront axle, being shown by dotted linesv in Fig. is denoted by the numeral 8; It 60 11s inclosed in sleeve 9, and is driven by differential gearing l0. The latter is located in the usual manner in a casing or chamber 11,` which is the enlarged middle partof sleeve 9. The same difierential gearing is driven by'rod 12, connectingwith an engine which is not s hownin the drawings. Sleeve 9 carries at each end a yoke 1'3, which is similar in construction to yoke 3, and comprises a casin 14 and an upward reaching arm 15. Eac of said casings 4 and 14 is closed, so as to5 exclude dirt and hold lubrieating oil, by means of anterior and posterior hoods, or covers, 18 and 19, which are fastened to the described lyokes by screws lower walls of said casingsl and 14;, and 8 through the terminal portions of said brackets 5 and 15. A sleeve 23, rotates on the middle of pin 17, and carrieson its opposite ends two bevel gea-1s, 24 and 25, which are located in said casings 4 and 14 respectively, and in mesh with said gears 7 an 8 respectively. Two arms 27, pro`ecting forward from yokes 3, are connecte by a link 28 and operated by a rod 29 in the usual manner to turn the vehicle wheels to inclined positions, indicated by broken lines in Fig. 2. Y Such being the construction and operatic of my invention, I claim- 1. A rotatory axle, which is driven by differential gearing, and is provided with terminal beveled gear wheels; a sleeve thereon, which carries at each end an upwardly extending bracket and a closed casing for one of said terminal beveled gear wheels; a pair of traction wheels, having rotatory stub axles, which are fastenedto the hubs of said tract-ion wheels, and are provided with bevel gears; al' nonrotatoryv sleeve which rides between the hub and stub axle of each traction wheel, and carries a. down-A wardly extending bracketand a closed casf 'l5 26 orthe like, as shown in Fig. 2.- The bot-v eled geni' wheels, and is foiiiieil in iwn seefioiis, rotatable mit of iiiiiseii; meines fur iii for one ef .Suid bevel gears; and a vei'tL capivot pin, which pasSes through both of i said brackets :imi belli of said veziSiiif' combiiiziiioii with :i geur sleevet which pivots said geur ensiiigs together, i'etxiteseu said pii't.- pin, and i5 previiled with terminal gears, meshing with siiiil beveled geni' Wheels :ind bevel gen1-s. i
